Description

Technical Field

[0001] This utility model relates to the field of power adapter thermally conductive potting compound production technology, specifically a high-temperature resistance testing device for power adapter thermally conductive potting compound production. Background Technology

[0002] Due to their operating characteristics, power adapters generate high temperatures when powered on, which accelerates the aging of internal components, affects their lifespan, and poses certain safety hazards. Therefore, during the design and production of power adapters, measures such as enhanced heat conduction, stable components, and fire and moisture protection are necessary. Silicone (potting compound) is commonly used in this process, hence the potting process. Automatic potting machines commonly use silicone as the potting material for the internal filling of power adapters.

[0003] For example, application number CN202122737383.9 describes a potting compound raw material tank and a power adapter potting compound, including a tank body, a sealing cap, a heating element, and a discharge piston. The tank body has a discharge nozzle at its bottom; the sealing cap is adapted to seal the opening of the tank body; the heating element is inserted into the wall of the tank body; the discharge piston is adapted to connect with the tank body, dividing the inner cavity of the tank body into an upper cavity and a lower cavity; a first air inlet is provided at the upper end of the tank body or the sealing cap, which is adapted to connect to the upper cavity. When cleaning the tank body, there is no need to clean the heating element, nor is it necessary to disassemble the heating element. Furthermore, a new potting method combining a discharge piston with a heated tank is provided. The discharge piston is used both for potting and for scraping the thermally conductive potting compound off the inner wall of the tank, eliminating the need for cleaning the inner wall of the tank. This potting method further reduces the workload of cleaning the tank body; the heating element does not need repeated disassembly and cleaning, extending its service life and allowing it to remain in a stable working state for a long time, thus improving production efficiency. However, the high-temperature resistance testing device for the production of thermally conductive potting compound for power adapters does not clean the electronic components of the power adapter before potting. Directly potting the power adapter can damage the stability and reliability of the internal components of the power module. Furthermore, the adhesive material stored in the storage tank tends to settle at the bottom, resulting in uneven mixing. Ordinary stirring mechanisms cannot effectively agitate the adhesive at the bottom of the storage tank, leading to poor mixing performance. Therefore, in view of these shortcomings, this paper proposes an improved high-temperature resistance testing device for the production of thermally conductive potting compound for power adapters. Utility Model Content

[0004] The purpose of this invention is to provide a high-temperature resistance testing device for the production of thermally conductive potting compound for power adapters, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistance testing device for the production of thermally conductive potting compound for power adapters, comprising a support rod and an electric conveying block. The support rod is externally connected to the electric conveying block, and a dust collection plate is fixedly connected to one side of the electric conveying block. An adapter body is provided at the bottom of the dust collection plate, and a base plate is provided at the bottom of the adapter body. A stirring display mechanism is provided on one side of the base plate.

[0006] Preferably, the adapter body includes an outer frame fixedly connected to the top of the base plate, and electronic components are fixedly connected inside the outer frame, and mounting holes are provided inside the outer frame.

[0007] Preferably, a connecting column is fixedly connected to the top of the base plate, and a movable frame is fixedly connected to the top of the connecting column.

[0008] Preferably, a movable block is movably connected inside the movable frame, and an electric cylinder is fixedly connected to the bottom of the movable block.

[0009] Preferably, a sealing plate is fixedly connected to the bottom of the electric cylinder, and a sealing hole is provided at the bottom of the sealing plate.

[0010] Preferably, the top of the sealing plate is fixedly connected to an elastic connecting tube, and one end of the elastic connecting tube is provided with a stirring display mechanism.

[0011] Preferably, the stirring display mechanism includes a storage box fixedly connected to one end of an elastic connecting tube, and a motor fixedly connected to the top of the storage box. The output end of the motor is provided with a stirring rod, and the outside of the stirring rod is provided with stirring blades. A temperature display meter is provided on one side of the motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the design of a dust-collecting plate and a stirring display mechanism, ensures that the surface of the power adapter is clean before glue application. The dust-collecting plate consists of a vacuum cleaner and a storage box. Before glue application, the electric conveyor block drives the dust-collecting plate outside the support rod to collect and adsorb dust from the surface of the power adapter, preventing dust from being sealed inside the power adapter during glue application, which would affect the adhesion of the glue and the lifespan of the power adapter. Traditional potting devices do not clean the electronic components of the power adapter before applying glue, and directly apply glue to the power adapter, which would... This can damage the stability and reliability of the internal components of the power module, and the colloidal material stored in the storage box is prone to settling at the bottom of the storage box, resulting in uneven mixing of the colloidal material. Ordinary stirring mechanisms cannot stir the colloidal material at the bottom of the storage box, resulting in poor stirring effect. The stirring display mechanism added in this utility model has stirring blades inside the box that come into contact with the bottom of the box to stir the colloidal material that has settled at the bottom of the box, preventing the colloidal material from settling. At the same time, the temperature display on the top of the storage box can monitor the temperature of the colloidal material inside the storage box, so that the colloidal material reaches the appropriate temperature before dispensing.

[0014] 2. This utility model, through the internal pump body and multiple sets of sealing holes of the sealing plate, applies pressure to the adhesive material when it is transported into the interior of the sealing plate, so that the adhesive material is evenly discharged through the sealing holes. Since multiple sets of sealing holes are added to the bottom of the sealing plate, the potting area of ​​the power adapter is increased, thereby increasing the coverage area of ​​the adhesive material on the power adapter and improving the potting efficiency.

An electric drive rod is provided at the center of the movable frame 7 to drive the movable block 8 to move left and right, so that the sealing plate 10 can fully pot the adapter body 4.

[0024] Furthermore, a sealing plate 10 is fixedly connected to the bottom of the electric cylinder 9, and a sealing hole 11 is provided at the bottom of the sealing plate 10.

[0025] Furthermore, the stirring display mechanism 13 includes a storage tank 1301 fixedly connected to one end of the elastic connecting tube 12, and a motor 1302 fixedly connected to the top of the storage tank 1301.

The motor 1302 is started, causing the stirring rod 1303 to drive the stirring blade 1304 to stir the potting material. When the temperature display 1305 shows a suitable temperature, the water pump at the bottom of the elastic connecting pipe 12 transports the potting material to the sealing plate 10. Then, the electric conveying block 2 drives the dust suction plate 3 to move outside the support rod 1 to remove dust from the surface of the adapter body 4.
